Standard Input-Output Norms for Copper & Lead Free Mirror on Float Glass prescribe permitted raw material options, process chemicals, alternative concentrations, and packaging items; allow a UV cured top coat only for UV coated exports; and require applicants to ensure imported inputs match those used in the declared export product, with authorities determining permissible proportions of inputs for different resultant products.
